motor mount problims

Got looking at my motor mounts tonight and thought well lets pull the 318 out to be sure they will fit from my 318 to my new 360.In the first 2 pics on the right side they fit,but on the left side its not going to work.I can only get two bolts on one side to fit but as you can see there is nothing on that 318 mount to bolt up at the top of the ear.What gives.

Ok so what your saying, take that mount weld on a piece and drill the hole to fit up top sounds like a simple job.But If I cant get someone fast fast enough to weld on to it.Could I just bolt some steel on that lower hole and than drill that top hole.I realy want to get tis in by Wednesday.Thanks.
